A radio access network (RAN) includes a first wireless access point that radiates to define a first wireless coverage area, and a second wireless access point that radiates to define a second wireless coverage area. A dual-mode wireless communication device (WCD), capable of communicating via both the first and second wireless coverage areas registers with the first wireless access point. As part of the registration process, or at some point thereafter, the first wireless access point transmits information that identifies the second wireless coverage area. The first wireless access point also transmits a WCD identifier received from the WCD during the registration process to the second access point, so that the second access point can add the WCD identifier to its whitelist. Thus, via the second wireless coverage area, the WCD can register with the second wireless coverage area.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: a first wireless access point wirelessly receiving a request from a wireless communication device (WCD), wherein the first wireless access point comprises a femtocell access point and defines a first wireless coverage area, wherein the request includes a WCD identifier that identifies the WCD, and wherein the WCD identifier comprises a media access control (MAC) address; and in response to the request, the first wireless access point (i) transmitting, to a second wireless access point, a whitelist of devices permitted to use the second wireless access point, wherein the whitelist of devices includes the WCD identifier, wherein the second wireless access point comprises a Wifi access point and defines a second wireless coverage area, and (ii) transmitting a reply to the WCD, wherein the reply contains identifying information that identifies the second wireless coverage area, wherein the whitelist is maintained by the second wireless access point, and wherein transmitting the whitelist comprises: the first wireless access point transmitting the WCD identifier to the second wireless access point; and the second wireless access point revising the whitelist to include the WCD identifier.
2. The method of claim 1 , wherein the first and second wireless coverage areas are substantially overlapping, and wherein the first and second wireless coverage areas are defined using different wireless access technologies.
3. The method of claim 1 , wherein the identifying information includes at least one of a service set identifier (SSID), a password, and a channel.
4. The method of claim 1 , wherein the reply comprises a short-message-service (SMS) message.
5. A system comprising: a first wireless access point configured to define a first wireless coverage area, and including a processor and a data storage, wherein the first wireless access point comprises a femtocell access point; a second wireless access point configured to define a second wireless coverage area, wherein each of first and second wireless coverage areas is formed using a different wireless access technology, wherein the second wireless access point comprises a Wifi access point; and program instructions, stored in the data storage and executable by the processor to (i) wirelessly receive a request from a wireless communication device (WCD), wherein the request includes a WCD identifier that identifies the WCD, and (ii) in response to the request, transmit, to the second wireless access point, a whitelist of devices permitted to use the second wireless coverage area, wherein the whitelist of devices includes the WCD identifier, and transmit a reply to the WCD, wherein the reply contains identifying information that identifies the second wireless coverage area, wherein the WCD identifier comprises a media access control (MAC) address, wherein the whitelist is maintained by the second wireless access point, and wherein the program instructions to transmit the whitelist comprise program instructions for the first wireless access point to transmit the WCD identifier to the second wireless access point, causing the second wireless access point to revise the whitelist to include the WCD identifier.
6. The system of claim 5 , wherein the identifying information includes at least one of a service set identifier (SSID), a password, and a channel.
7. The system of claim 5 , wherein the first and second wireless coverage areas are substantially overlapping, and wherein the first and second wireless coverage areas are defined using different wireless access technologies.
8. The system of claim 5 , wherein the reply comprises a short-message-service (SMS) message.
9. A method comprising: a first wireless access point wirelessly receiving a request from a wireless communication device (WCD), wherein the first wireless access point comprises a Wifi access point and defines a first wireless coverage area, and wherein the request includes a WCD identifier that identifies the WCD, wherein the WCD identifier comprises a mobile directory number (MDN) or a mobile equipment identifier (MEID); and in response to the request, the first wireless access point (i) transmitting, to a second wireless access point, a whitelist of devices permitted to use the second wireless access point, wherein the whitelist of devices includes the WCD identifier, wherein the second wireless access point comprises a femtocell access point and defines a second wireless coverage area, and (ii) transmitting a reply to the WCD, wherein the reply contains identifying information that identifies the second wireless coverage area, and wherein the whitelist is maintained by the second wireless access point, and wherein transmitting the whitelist comprises: the first wireless access point transmitting the WCD identifier to the second wireless access point; and the second wireless access point revising the whitelist to include the WCD identifier.
10. The method of claim 9 , wherein the identifying information contains a frequency or a channel.
11. The method of claim 9 , wherein the reply comprises a Dynamic Host Configuration Protocol (DHCP) reply, and wherein the identifying information is contained within a DHCP option.
12. The method of claim 9 , wherein transmitting the reply to the WCD further comprises: the second wireless access point transmitting the identifying information to the first wireless access point; and the first wireless access point transmitting the reply to the WCD.
13. The method of claim 9 , wherein the first and second wireless coverage areas are substantially overlapping, and wherein the first and second wireless coverage areas are defined using different wireless access technologies.
